Measuring Freezing Point Principle

According to the methods, the sample is cooled down and stirred. The solid hydrocarbon crystals formation are detected by means of a light beam reflected thanks to a mirror. As soon as crystals are detected, the sample is warmed up until their complete disappearance.

 

Measuring Freezing Point Devices

• Light pulsed emission on I.R spectrum through a coaxial fibber optic
• Coaxial fibber optic equipped with a mirror

Measuring Temperature Probe

• Platinum resistance PT100 class A

Stirrer
